CONDUIT FOR CABLE ROADS.

SPECIFICATION forming part of Letters Patent No. 322,766, dated July 21,1885.

Application filed May 2, 1885. (No model.)

To @ZZ whom it may concern..-

Be it known that I, JAMES WARNER, a subject of the Queen of GreatBritain, having resided one year last past in the United States, andmade oath of intention to become a citizen,a resident of the city andcounty of Philadelphia, State of Pennsylvania, have invented a new anduseful Improvement in Gonduits for Cable Roads, which improvement isfully set forth in the following specication and accompanying drawings,in which- Figure l represents a top or plan view of a conduit for cableroads embodying my invention. Fig. 2 represents a side elevationthereof. Fig. 3 represents a vertical section in line a: fr, Fig. 2, onan enlarged scale.

Similar letters of reference indicate corresponding parts of the severalfigures.

My invention consists of a conduit for a cable road having its slotadapted to be adjusted in width, as will be hereinafter fully set forth.

Referring to the drawings, A represents'a conduit for a cable road, thesame having sides and a bottom of suitable metal or material properlybolted,riveted, or otherwise secured together.

B C represent the slot-irons, the iron B being stationary and the iron Cmovable to and from the iron B, whereby the Width of the slot may beadjusted. The iron C rests on a plate or flange, D, projecting from thetop of the side ol' the conduit and formed therewith or secured theretoin any Suitable manner.

Depending from the iron C are ears E, having threaded openings withwhich engage the screw-bolts F, it being noticed that the iron D isformed with transversely-extending slots G, which receive said ears andpermit the play of the same during the adjustment of the iron C.

At the outer side of the plate D is a depending flange, H, to which thebolts F are swiveled, whereby, by the rotation of said bolts, the ears Emay be moved in the slots G, the iron C, as is evident, moving with saidears.

It will be seen that the width of the slot of the slot-irons may beincreased or decreased by properly rotating the bolts, so that the samemay be adjusted relatively to the nature of the grip, the action of heatand coldy on the slot-irons, and other necessities of the case, thisbeing accomplished without enter- 5 ing the conduit or removing theslot-irons, it being noticed that the heads of the bolts F, whenuncovered, may be readily reached and operated by a wrench or key fromthe top of the street.

In order to retain the bolts in position on the flange D and guard theheads of the same, I employ keepers J, which are secured to the saidiiange and overlap the heads of the bolts, s o that said heads abutagainst said keepers, without, however, preventing the bolts fromrotating freely in the openings or slots K in the flange and operatingthev ears E, said keepers, in connection with the flange H, serving toswivel the bolts F in 7o position. y

In order to permit the longitudinal eXpansion and contraction of theiron C, the openings or slots K in the flange H are enlarged in thedirection of the length of the iron, so that the bolts F are permittedto move in said openings as the iron expands and contracts.

If desired, the slot-iron B may be adjustable similarly to the iron C.The ends of the irons are prevented from lateral displacement by havingmortised joints, as seen in Fig. 2.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. A conduit for a cable road having the slotted plate D, in combinationwith the movable iron C, having ears E, and resting on said slottedplate D, substantially as described.

2. In a conduit for a cable road, the slotted plate D, having ange H, incombination with movable iron C, having ears E, and bolts F, swiveled insaid iiange H, substantially as and for the purpose set forth.

3. In a conduit for a cable road, the slot- 95 ted plate D,having slotG, and depending flange H, in combination with movable iron C, havingdepending ear E, working in said slot G, and screw-bolt F, swiveled inthe iiange H, and playing or operating in a threaded open- 10o ing inthe ears E, substantially as and for the bolts, substantially as and for`the purpose set purpose set forth. forth.

4. In a conduit for a cable road a movable slot-iron, a supporting-platetherefon JAMES WARNER 5 bolts connected with said plate and engagingWitnesses:l

with the slot-iron, and keepers connected JOHN A. WIEDERSHEIM,

with the plate, inclosing the heads of the JNO. K. PLITT.
